Anneal, grind to about 120 grit, draw file, grind out all possible stress
risers, normalize, harden, stress relive, final grind with out gloves to
insure you don't over heat the blade, stone, wet paper finish down to about
600 grit using water laced with 409, cool mist etc., degrease, etch in a 140
F. mix of 1 part ferric Chloride to 3 parts warm distilled water, boil in
distilled water,neutralize in Tri Sodium Phosphate solution, spray down with
WD-40. and rub vigorously with brown paper shopping bag several times a day
for 3 days, light polish with 1200 grit paper to high- light the etch, spray
down with fluid film and presto you are ready to fit your handle etc.

> Greetings,
> I have just finished rough forging my first pattern welded blade (and
> don't anyone dare say Damscus).  It's pretty close to final shape but I
> left enough to do the final grinding.  As this is my first forged knife

> In what order should I now do the grinding, normalizing (thermal cycling 3
> times) and hardening/tempering?  I'll probably normalize before grinding
> just to be sure so that I can tap out the small kinks, but should I
> normalize after grinding again?  Heat treat before or after
> grinding?  Polish after heat treating?  Acid etch last?
> This is a small Viking style knife that with a whittle tang going into an
> antler handle.
> I'm really looking forward to the advice and to finishing my first knife.
